This
teacher-directed
demonstration
provides
a
conceptual
understanding
of
latent
heat.
Using
the
example
of
a
chemical
hand
warmer,
students
learn
about
phase
changes
from
liquid
to
solid
and
from
solid
to
liquid
and
observe
that
one
of
these
phase
changes
releases
heat
while
the
other
requires
heat
to
be
added.
These
concepts
are
then
reinforced
in
a
demonstration
which
involves
heating
water
and

In
this
lesson,
students
learn
about
the
varying
sizes
of
ocean
waves,
what
causes
such
variation,
and
where
to
find
giant
waves.
Students
will
learn
the
parts
of
a
wave,
and
discuss
wave
height,
wavelength,
and
wave
period.
They
will
explore
variables
that
influence
wave
size
through
scientific
visualizations.
They
will
then
experiment
with
creating
waves
on
the
National
Geographic
Wave
Simulator

This
set
of
resources
for
younger
students
includes
activities
and
information
on
thunderstorms,
tornadoes,
hurricanes,
blizzards
and
clouds:
how
they
form,
and
how
they
impact
our
lives.
There
are
games
about
clouds,
stories
about
extreme
weather
events,
and
a
set
of
activities
in
which
students
create
simulations
of
various
weather
phenomena
such
as
fog,
clouds,
tornadoes,
and
others.

This
interactive
site
features
games,
animations,
and
teachers'
materials
intended
to
introduce
younger
students
to
climate
change.
There
is
information
about
what
climate
change
is,
the
difference
between
weather
and
climate,
and
the
greenhouse
effect.
There
are
also
materials
on
the
climate
system,
ancient
climates,
and
how
scientists
investigate
climate.
Other
topics
include

The
purpose
of
this
activity
is
to
build
an
instrument
that
can
be
used
to
measure
water
temperature.
Students
construct
a
soda-bottle
thermometer,
which
is
similar
to
the
thermometer
used
by
GLOBE
schools.
Both
are
based
on
the
principle
that
most
substances
expand
and
contract
as
their
temperature
changes.
This
experiment
also
demonstrates
the
principle
of
heat
transfer.
The
intended
outcome
is

This site offers a virtual walk-through tour of a hydroelectric facility. The creation of hydroelectricity begins at the dam, where the power plant converts the force of falling water into electricity. It shows how dams operate and the equipment necessary for electrical generation.

This
project
gives
students
the
opportunity
to
appreciate
how
difficult
it
is
to
predict
the
weather
when
making
forecasts.
By
accessing
an
assortment
of
images
and
data,
the
students
will
be
asked
to
forecast
on
a
regular
basis
and
determine
the
accuracy
of
the
forecasts
by
comparing
them
with
the
actual
observed
data.
Students
will
also
complete
specially
constructed
activities
that
introduce

This
site
provides
an
overview
of
the
Earth's
atmospheric
greenhouse
effect
by
briefly
exploring
the
atmospheres
of
nearby
planets
and
discussing
the
greenhouse
gases
of
our
atmosphere,
such
as,
water
vapor,
carbon
dioxide,
methane,
ozone,
and
nitrous
oxide.
Students
will
learn
that
the
heat-trapping
ability
of
a
greenhouse
is
influenced
by
a
number
of
factors,
including
the
transparency
of
the
greenhouse

This
hands-on
demonstration
of
the
communications
path
between
scientists
and
the
NASA
Extreme
Ultraviolet
Explorer
(EUVE)
Satellite
shows
how
scientific
data
are
downloaded
from
the
satellite.
The
same
demonstration
can
also
be
used
to
illustrate
how
the
instruments
on
the
satellite
are
commanded
by
scientists
on
Earth.
It
gives
students
a
